A heat powered fan for wood stoves is essential for surviving the harsh winter. It effectively distributes the warmth from the stove throughout your entire house, allowing you to enjoy the cozy comfort of your sofa or bed.

However, there are instances when the wood stove fan fails to function properly. By carefully reading the user guide for your heat powered wood stove fan, you can identify certain points to consider when using it.

So, why isn't your stove fan working, and how can you determine the cause?

Here are some key factors that can cause the wood stove fan to stop, based on the expertise of VODA, who has been specializing in heat powered wood stove fans for over 12 years.

1.Low Temperature:

To understand why your wood stove fan doesn't work when the temperature is low, it's important to know how the fan operates.

The fact that a wood stove fan functions without requiring electricity may seem like magic. However, it's actually due to the thermoelectric motor. When there is a temperature difference between the base and the top of the fan, it generates a low voltage that powers the blades.

If the voltage is too low to operate the fan, it will not work. The fan can only function within a specific temperature range, which varies depending on the model. For example, VODA heat powered wood stove fan operates between 55℃ and 345℃. If the temperature falls below the minimum threshold, such as 45℃, the fan will not work. As the wood burns and the temperature rises above 55℃, the blades start circulating the heat.

Therefore, if your wood stove fan doesn't work immediately after installation, don't worry. As the temperature increases, the fan will start functioning.

2.Insufficient Airflow:

The fan operates by rotating its blades, which in turn pushes the air from behind to the front.

If you place the heat powered wood stove fan against a wall or the chimney, it will fail to function properly.

To ensure optimal performance, it is recommended to position your wood stove fan on either the left or right side of the chimney, leaving a few inches of space behind the fan (as shown in the picture below).

3.Motor Damage:

The thermoelectric cell of the heat powered wood stove fan can be damaged by high temperatures, and this damage is irreversible.

To prevent such damage, it is advisable to use a fireplace thermometer in conjunction with your heat powered wood stove fan. This will allow you to monitor the temperature accurately. When the temperature approaches the highest rated limit, either relocate the stove fan to a cooler spot or reduce the amount of fuel in the stove to cool it down.

By considering these factors and taking appropriate measures, you can ensure the optimal functioning of your heat powered wood stove fan.
